It is a sensitivity to something from Covid not an allergy. Try Zyrtec and Pepsid together in the morning and the evening. You can also try it mid-day and see if that helps. You really need to get someone to run some bloodwork on you to see what if any viruses you have in your system and if they are setting it off. You would need to see an infectious disease specialist for this.
